Abstract
PURPOSE: To obtain the titled compound useful as an intermediate for synthesizing a light stabilizer for high polymer materials, drugs, etc., in high yield in high purity, by reacting acetone or an acidic condensate of acetone with acetonin by the use of a phosphorus halide or a sulfur halide.
CONSTITUTION: Acetone or an acidic condensate of acetone (especially diacetone alcohol) is reacted with acetonin, namely 2,2,4,4,6-pentamethyl-2,3,4,5- tetrahydropyrimidine, in the presence of a phosphorus halide such as phosphorus trichloride, phosphorus pentachloride, phosphorus oxychloride, etc., or a sulfur halide such as thionyl chloride, sulfuryl chloride, sulfur monochloride, etc., as a catalyst, to give 2,2,6,6-tetramethyl-4-oxopiperidine.
EFFECT: A small amount of a catalyst is required and a reaction time is also short.
